Transferring an already registered domain name entails switching the domain registrar that provides the registration service, so after the transfer itself, you will have to manage things like renewal fees or DNS entry updates through the new domain registrar. The transfer process is standard with most TLD extensions. Some country-code extensions are more specific and involve different steps, but in the general case transferring a domain name involves a few necessary steps and one of them is unlocking the domain name. The domain lock is a safety feature, which is being embraced by more and more domain registry operators. It’s a default feature supported by all generic TLDs. If a domain name is locked, it will not be possible to initiate a transfer process, so nobody can even attempt to snatch your domain. The domain lock can be annulled only through the account where the domain is registered and all new domains that support this feature are locked by default the moment they are registered.
